  • 1.  trunk port beetwen aruba switch & cisco

    Posted Mar 24, 2022 01:07 AM
    Hello, I want to configure a link trunk between a Cisco switch and Aruba. BUT I CAN'T do it, what could I be doing wrong, the connection between aruba and cisco is through port 24 (aruba) and 36 (cisco)

    Cisco:

    interface vlan 1
    name GESTION
    ip add 10.1.2.1 255.255.255.0
    no shut

    interface vlan 5
    name USERS
    ip add 192.168.1.1 255.255.255.0
    no shut

    (config-if)#interface Gi1/0/36
    Switchport mode trunk


    Aruba:

    trunk 24 trk1 trunk

    vlan 1
    name GESTION
    untagged 5,Trk1
    ip address 10.1.2.2 255.255.255.0
    exit

    vlan5
    name USERS
    untagged 23
    tagged 5,Trk1
    no ip address
    exit

    Hi Christian,

    I think you are confused because of the difference in the terminology used by cisco and procurve. The following document will throw some light on that:
    https://support.hpe.com/hpesc/public/docDisplay?docId=c02777559&docLocale=en_US

    Trunk on cisco means tagged port on procurve devices. Trunk on procuve is port channel/ link aggregation. 

    In your case you have to just add the desired port as tagged member of the vlan on the procurve side (you have to delete the Trunk on the procurve and just assign port 24 as tagged member of vlan5).

    Make sure you also have your L2 vlan created on cisco. Your config on the cisco switch shows the configuration of the L3 SVI, but you also need to create the L2 VLAN with "vlan 5" command in config t. You can confirm this with a "show vlan"

    Hi, do as indicated, but no ping between 10.1.2.2>10.1.2.1

    ARUBA::
    vlan 1
    name "GESTION"
    no untagged 1-2
    untagged 3-23,25-52
    tagged 24
    ip address 10.1.2.2 255.255.255.0
    exit

    vlan 5
    name "USERS"
    untagged 1-2
    tagged 24
    no ip address
    exit

    CISCO:
    #SHOW VLAN
    VLAN Name Status Ports
    ---- -------------------------------- --------- -------------------------------
    1 GESTION active Gi1/0/15
    5 USERS active Gi1/0/13, Gi1/0/15, Gi1/0/16, Gi1/0/17, Gi1/0/23, Gi1/0/33, Gi1/0/44


    interface vlan 1
    name GESTION
    ip add 10.1.2.1 255.255.255.0
    no shut

    interface vlan 5
    name USERS
    ip add 192.168.1.1 255.255.255.0
    no shut

    (config-if)#interface Gi1/0/36
    Switchport mode trunk

    Can you share your port mapping? What port is connecting to what port on each.

    Shure:

    Its only this
    Cisco  Gi1/0/36 <> Aruba port 24  


    In aruba:

    switch(config)# show vlan port 24 detail

    Status and Counters - VLAN Information - for ports 24

    VLAN ID Name       | Status        Voice   Jumbo  Mode
    ------- -------------------- + ----------    -----       -----    --------
    1             GESTION | Port-based  No      No      Untagged
    5              USERS     | Port-based  No      No      Tagged

    Could you please share the following outputs:

    Procurve:
    show vlan 1
    show ip

    cisco:
    show interfaces g1/0/36 switchport
    show interfaces g1/0/36 status
    show ip interface brief

    Share more details on how you are performing the ping tests?

    Aruba Port 24 should have the same native (untagged) vlan as the cisco port 1/0/36. Since you did not specify a native vlan on the cisco port, it will default to vlan 1 as the native. Trunks should have the same untagged vlan on both sides of the trunk link. Your output originally did not show this.

    On the Aruba switch Configure the following:
    config t
    vlan1
    untagged 24
    vlan 5
    tagged 24

    On the Cisco switch Configure the following:
    config t
    vlan 1
    exit
    vlan 5
    exit
    int gi1/0/36
    switchport mode trunk
    switchport trunk native vlan 1
    switchport trunk allowed vlan all
    end
